Investors expect limited future growth, contributing to the low P/S ratio. Shareholders accept this as they believe future revenue won't provide pleasant surprises. These conditions form a barrier for the share price.

Despite high reinvestment, the low ROE and declining net income suggest it's not benefiting investors. Caution is advised due to negative impact on earnings growth and potential business risks.

Shenzhen SED Industry Co. exhibits a major buying opportunity as its market valuation is below intrinsic value with high price volatility. Future revenue growth signposts a promising outlook unreflected by current share price.
